Further profile syncing?

[floris]

In light of #1828, would it be good to 'honour' the WP and MU profile fields a bit more with syncing switched on?

Should work now on registration (almost)?
BP username --> WP username
BP name --> WP first name
BP name --> WP nickname
BP name --> WP display as

Should be added/changed, incorporate predefined fields (optionally added to base)?
BP first name --> WP first name
BP last name --> WP last name
BP display as --> WP display as

Could biographical be added as a second (optional) field group in BP?
BP all biographical --> WP all biographical

Means optional predefined fields or field groups need to be created which can pass this info to WP. Thinking BP profile via WP to other plugins. Know there are some tools around, but would BP core be preferable?

We sync display name because it is needed by BuddyPress throughout the interface: in the activity stream, in notification emails, etc etc etc. The same cannot be said for any other of the values that WP natively collects. Even first name and last name are outliers, because they're not going to be useful in the same ways across languages. And the additional fields - things like ICQ - are things that many/most BP communities do not need/want as public profile fields.

It's possible to force any pair of fields to be synced in a plugin, and in the absence of a counterargument, I think that's good enough.
